AUTOMATIC FEEDING DEVICF FQR PLATEN PEINTING-PRESSES.

' To all eviwm it may concern:

Be it known that I, HANS'HONIGMANN, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and'nseful' Improvements in Automatic FeedingDevices Presses, of which the following is a specification, referencebeing had therein to the accompanying drawing.

My invention relates to lmprovements' in automatio' feeding devices forplaten printing presses.

The object of my invention is to provide an automatic feeding, deviceconnected to and operated by the'press, in which the sheets of paper arefed from the stack and carried to the press, and in "whichthe'previously printed sheet is simultaneously removed and stacked inanother place upon each operation of the platen of the press.

Another object of my invention is topro- 'vide a stacker of thischaracter so constructed and arranged that the swinging or movingthereof into operative position couples the working part thereof withanecessary working part of the press for operating the feeder, wherebythe feeder can be readily thrown into or out of operation and when sodesired the press can'be fed by hand, Y

A still further object of my invention is to provide a feeder of thischaracter which is simple inconstruction and efiective in operation andneeds no attention after set in operation except to place the stack ofpaper to be printed upon.

In the accompanying drawings: Figure 1' of the drawings is a top planview of my improved feeder, illustrating in detail only those partsessential to my present invention. F ig.-2 is a front elevation of Fig.1, looking in the direction of the arrow. Fig.

gaging member. Fig. 10 is an enlarged side elevation of the sheetaccelerating means, with a portion of the stock apron in section. Fig.11 is a side elevation of the air pump connection.

Referring now to the drawings,1 represents the pivotal eenter upon whichthe feeder frame is mounted. This pivotal center is carried by an ear1'- and is adapted to rest upon an outwardly extending ear carried bythe frame of the platen printing press and so arranged that it can beswung around so as to bring the feeder into opera--- tive connectionwith the printing press and at the same time so position it that it willfeed the sheets of paper from thestack to- "the platen of thepress, aswill be hereinafter more fully described. ,he feeder frame 2 consists ofside-walls and 3 and ,cross bars 4, 5', and 6', and is mounted adjacentthe platen 7 of a printing press, such as is described and shown in myPatents Numbers 970,822 and 1,074,720.

The sheet manipulating mechanism, which will be hereinafter more fullydescribed and mounted within the feeder frame 2 is operated in unisonwith the operation of the press in any desired manner, preferablythrough the medium of suitable gear wheels Sand -9, which are mountedupon the main shaft 1 0 of the feeder, and which shaft is continuouslyrotated when the feeder is in operation. The shaft 10 being operated bythe press is timed with the platen 7, whereby thefeeding mechanism isadapted to @operateat the proper time to remove the printed sheet fromthe platen and simule taneously place another sheet in positionthereonto be printed.

The shaftlO isrotatably mounted within the walls 2 and. 3 and extendsacross the feederframe .and adjaicent the wall 2 has i fixedthereuponi-the'fram 13 engaging a roller 14rm0untedvvithin the-upper endof means of sliding rods 23-23 which reoipro- I cate vertically withinthe guides 242 i car ried by the shaft 25, rigidly supported be tweenthe side walls 2 and 3 of the feeder frame and extending across thesame. By thisstructure it is seen that the shaft 22 with its Variousattachments will remain normally at the lowermost extremity of itsstroke and, toassist such downward tendfency, a spring 26' maybeutilized which would exert inward draft upon the crank arms 17 asclearly shown in Fig, 8.

The shaft 10, adjacent the sidewall 3 of the feeder frame has fixedthereon a second cam 27 engaging with and actuating the rol er 28carried by the free end of the crankarm 29 which is rigidly fixed to theshaft 22 and whereby the said crank arm is oscillated through the powerimparted by the.

undulating shape of the cam 27, this shape being such as to impart theproper motion to the crank arm 29 at the'proper time to 'be-in step withthe other working parts of the mechanism, as will be hereinafter morefully described. Slidably and adjustably fixed on the shaft" 22 on theinside of the arms 29, are the hubs 31, in which are adjustably mountedthe downwardly extending rods 30 having at their lower ends theadjustable suction cups 32. These cups are adjustable-in th'atflthey areoffset laterally somewhat from the ends of the rods 30, by means ofthearms 33, and which armsare screw-threaded upon the endsof the rods 30and radially adjustable thereon. The arms 33 are hollow and communicatewith the suction cups 32 at their outer ends and their inner ends areprovided with a nipple 34,. upon which is placed the air suction tubes.35, which lead fromthe suction pump 35.

The construction and operation of this pump will be hereinafter morefully described; By this structure it will be seen that when the suctionis caused or'developed in the pump 35', there will be a suction in thetubes 35 1 and also in the arms 33 and cup 32, whereby when the cupsengage the uppermost sheet of the stack of paper, it will pick the sameup and convey it therewith to the proper place, which will he later.described;

The stock apron or shelf 36 isremovably supported within the feederframe and has its forward edge abutting the rear edge of the cross-bar 5and inclined to properly feed the sheets downwardly toward the. rearwall of the. bar. 5, as clearly shown in Figs. 3, and 100i the drawings.The stock apron or shelf 36 is provided with side wings 37 mounted upona cross-rod 38, carried by the brackets 39 at the sides of the apron 36.By this structure it will be seen that the wings 37 may be movedinwardly or outwardly to engage the edges of the stock of paper forreceiving sheets of paper of different sizes. The forward end of eachside wing is provided with an extension 40, having a hollow chamber 41therein terminating externally at its rear end into the elongated nipple42, upon which is placed an air-supply pipe 4:3 and through which ablast of air passes,

aswill be p rescntlydescribcd. The forward or outer. end of the hollowchamber 411 is provided with a vertically lateral slot 44 through whichthe blast of air passes to the edge of the stock-pile carried by theapron 36 for the purpose of slightly lifting or freeing the uppermostsheet from the pile when it is first lifted therefrom and avoid theattraction of the'secondsheet. The extension 40, in its inner face inrear of the vertical slot 44, is provided with a vertically disposedconcave recess 45,-to permit th escape of any super-confined air whichmay be forced intermediate the sheets and also to prevent the air-blastfrom unduly exercising the sheets. These recesses'also admit of apartial release of adhesive force when it becomes necessary to place thesuction cups in a position overlapping the edges of the stock pile andslightly projecting within such recesses. In order to still furtherprevent any possibility of the disarrangement of the sheets, I providethe extension 40 of the apron 36 with the inby the action of the pawl51engagingthe' ratchet 52, formed upon the periphery of the shaft-18.The pawl 51 is pivotallysupported at 53 within the free bifurcated end54 of the crank arm 55. This crank arm 55 is loosely mounted upon theshaft 56 and the opposite end 57 of the cranlearm carries a roller 58,which engages the cam 59 rigidly fixed upon the shaft 10, and said cam59 being timed with the running mechanism so that the friction roller 50is rotated at the proper time. 'izThe rotation of the shaft 18 arravae gand roller 50, 'heretoforedescribed, by the fore'j'the further rotationof theshaft and roller through the medium of the spurwheel 60, advancesthe rack. The spur-gear 60 is fixed to a disk 61 loosely mounted uponthe shaft 18 adjacent the ratchet and which gear carries the bar 62,which carries the reciprocating members, the construction of which isoldand needs no further description Themotion fromthe disk 61 is Tm.

parted to the shaft 18, by means of a plural ity of small pawls 63pivoted uponthe disk 61 and which engages the ratchet 52 adjacent thepawl 51. By this structure it will be seen that the pawl 51mayrevolvethe shaft 18 independent of the disk 61 and vice versa', wherebythe roller 50 may be set in motion to start the sheet, as heretoforedescribed. upon asuitable arm 65, which is lowered below the stock apronand is constructed. and arranged to intermittently bear upwardly at thepropertime against the roller 50, so that the said roller will engage orcome, in

2 contact with the sheet.

In order to checkor retard the motion of the sheet as it leaves theextension of the apron 8 6, I have provided a member 66, which has itsouterends, 66 turned upwardly, as" clearly shown 'in- Fig. 10 of thedrawings.

These ends, as shown, are on either side of the roller 64, the members66 are rigidly attached to the cross-shaft 67 and carried by said shaftis a crank arm 68 connected at 69 to the vertically disposed pitman 70..The upper end of the pitman is provided with a roller 71, whichengagesand derives its power from a cam 72, fixed upon the'sh'aft 10. aThis cam is so shaped and arranged upon the shaft 10 as to depress the.member66 at the proper time for the sheet delivery. The members 66 arenormallyheld in an upward position by means of a suitable spring 73intermediately attached-to the radial arm of the crank 68, and theopposite end of the spring connected to the bar 4, of the feeder" frame.Byxthis structure it willbe seenthat the member 66 is normally heldinits upward positiontoretardthe sheet as it leaves the memberfi, but isdepressed at the proper time by the cam 7 2 to allow-the sheet to pass.

The reciprocating sheet conveying member 74, consistsof an, elongatedmemberpivoted at its rearend to the rack-62 and whereby thereciprocation of .the rack, heretofore .described, will cause the sheet.conveying member. to reciprocate for removing the printed sheets fromthe platen 7 to the conveyer 12', from which they are discharged uponthe stack, not shown, in rear of the said conveyer; The. outer end ofthe recip A second roller 64 is mounted rocating member 7&1 is providedwith a bowshaped gripping member. .7 5 fixed to the shaft 76, which inturn is rotatably mounted within the olfset'finger 7 7 of thereciprocating member. Thisshaft 76 also carries a downwardly dependingfinger 78, designed when not engaging the face of the platen toslightly. rock the shaft'76 and thereby lift the knuckle 79 of thebow-shaped gripping member 7 5 from engagement with the reciprocatingsheet conveying *member 74, as clearly shown in Fig. 9 of the drawing.Releasing by contact with the platen only occurs as the sheet is aboutleaving the reciprocating elements and turning their backthe shaft 7 6and attached in. such a manner as ,to keep the gripping member normallyin'contact with the reciprocating member- 7 l'and to insure of the firmholding of the sheet when thus engaged.

In order to cause a suction for the suction cups 32 and also anair-blast for the member 40, heretofore described, I have provided arotating shaft 85 having mounted thereon a disk 85 provided witha'wrist-pin and to which is pivotally connected the pitman 84. Below thepitman 84 is a pump 35 pivotally connected at 86 to a stationary part ofthe printing press frame 87 and which is adapted to furnish thenecessary air required in the operation of' the feeder. Connected attheupper and lower ends of said pump are the two pipes 88 and 89, which,as heretofore stated, lead tothe connections 35 of the suction-cups andalso to the connections 43 of the. stock table and which needs nofurther description.

The operation of my device is as follows: The feeder is normally heldout of operation with the press, whereby the press may be fed .wardlytoward the press upon the pivot so that the gear wheels engage the gearcarried by the press and the gears so timed with the operation of theplaten 7 of the press, that a previously printed sheet is removed fromthe platen by the reciprocating member, 74 and a second sheetsimultaneously fed to the platen, which I will now proceed to describe,-The stock is piled upon the apron 36, as heretofore described, and theguides 37 are moved inwardly so as to hold the stock against lateralmovement. The starting of the press causes the shaft 10 to be set inoperation-,- which in turn starts theracks 62' lOO m ously withthisoperation a blast of air isforced through the pipe 43, which aidsinplaten' of the press.

outwardly so as to move the reciprocating sheet conveying memberoutwardly over the platen 7. of the press to'remove the previouslyprinted sheet inwardly by the memher-83, -shown =inIFig..9 of thedrawings. Simultaneously with thebperation of this outward movement ofthe reciprocating sheet conveying member 7 4, the suction cups 32.movedown upon the top sheet of the pile or stoclr and is slightly raised,lifting with Simultaneliftingthe top sheet from thepipe of the stock.Simultaneously with this movement the cam 27 allows the arm 29 to swingdownwardly which swings the suction cups 32 outwardly and conveysthe'top sheet of the stock outwardly upon the member 5; Simultaneouslywith this movement the continuously operated shaft 10 has brought-thecam 37 into a position to orce tbeintermediatelyi pivoted lever 54upwardly so that.

the pivoted rack 51 is forced forward engaging the ratchet wheel 52 onthe shaft 18,

and-causing a partial rotation of the shaft and the roller 50 carried bythe shaft 18,

will make a partial rotation, engaging the sheet still being held by thesuction cups 32 and deliver the sheet to the reciprocating member-74L,which conveys the sheet to the The stop 66 having been depressed throughthe medium of the crank 68, the pitman TO-and cam 72 allow the sheet topass from the member 5.
